Release Notes for the Cisco WAN Manager, Release 15.3.00 P1
OL-11190-01, Rev. C0
CWM Feature Limitations
• Only 15-minute collection buckets are supported for PNNI statistics.
• Peak statistics are not supported for PNNI statistics.
• If the PXM45 release is less than 4.0(0.0) PNNI historical statistics can not be enabled.
• The BPX-SES does not support PNNI statistics collection.
• The CWM does not support statistical alarms for lines on PXM45-based MGX nodes.
• The following statistics for SRM and SRM/E T3 lines can be enabled on the switch, but are not
supported by SCM: 28 dsx3LCVCurrent, 29 dsx3LESCurrent, 30 dsx3LSESCurrent,
31 dsx3PCVCurrent, 32 dsx3PESCurrent, 33 dsx3PSESCurrent, and 34 dsx3CCVCurrent.
• HP OpenView is supported on the SSM. The SSM processes generate CWM traps.
• At least one CWM must be running, with the nodes synced up, for the SSM to work properly. The
SSM uses the CWM server to get traps while enabling statistics for cell bus service modules on the
MGX 8850 and PNNI statistics on the BPX.
• The WANDEST server must be up and running on the CWM. The SSM gets the node, node_info,
card, network, rsc_part, and bis_object tables from the CWM by using WANDEST.
• If the statsmaster SSM or CWM is down or unreachable in an SCM gateway setup, the statsmaster
must be changed on the switch to another CWM or SCM that is up. The statsmaster is needed for
SCM statistics enabling or disabling.
• In an SCM Gateway setup with statistics collection in process, the old statistics data is not moved
to the new primary CWM or SSM machine after switchover.
• The SSM does not receive traps on Node/Card deletion, so statistics collection must be stopped and
disabled before deleting a node or card from the network. Also the SSM does not receive traps on
node or card Add messages, so the WANDEST upload must be received before the node or card can
be seen in the SCM GUI on the SSM.
• In the SSM, statistics collection must be stopped and restarted after changing the node name or
changing the node FTP password.
• Statistics data is stored on in statsdb database.
• Statistics parsing is only supported for the statsdb database on the SSM and the CWM. Statistics
parsing is not supported for the stratacom database on the SSM and the CWM.
• Stop statistics collection before upgrading a node image.
CWM-to-CWM Communication Limitations
This section describes CWM-to-CWM communication limitations:
• The secondary CWMs have to wait for the primary CWM to finish syncing up with the network.
Trap 28075 (svDatabaseInSync) is sent when the primary CWM has finished syncing up with
the network.
• All the CWMs managing the same network must have seed nodes or gateway nodes that have IP
addresses within the same network. All the CWMs should not all point to the same gateway node,
but the gateway nodes they point to should be on the same network.
• If an IP address is entered as gateway in the network.conf file and the DNS entry is missing for the
gateway node IP address, the Auto-Route network is not discovered.
